The `parserNS` argument to `parse` is an `Object` whose keys are XML namespaces and whose values are `Objects` whose keys are local element names and whose values are functions. A simple example might look like this:
```js
var parserNS = {
const parserNS = {
'http://my/first/namespace': {
'elementLocalName': function(/* ... */) {
// parse an <elementLocalName> element in the http://my/first/namespace namespace
